For some reason, I had visualized 30,000 calories worth of food still being a relatively "small" amount - at least something you could reasonably fit in front of one person. I guess it's because of all the times I've laughed at friends and their 1,000+ calorie McDonalds or Burger King trips. I can't imagine anyone fitting 30 times that in their stomach, even over a two hour period. When they listed off everything she stuffed down her throat, I was stunned for a moment.
IMO, this is someone that has been overweight all / most of their life, and at some point said to themselves, "Well, I don't have the willpower to lose the weight, so I'll just say that I'm happy being fat and try to gain as much as possible. Then I'll be famous!"
